Launch: This unit is on Ecology. To begin the study of this unit, each child will create a K-W-L chart on the topic of Ecology. To start with, each child will fill out the "K" portion of their chart to show what they already know about Ecology. When they have finished writing down all that they know about Ecology, they can begin the next column, which is the "W"- what they want to know about the topic. After the first two columns of the chart have been completed by every child, we will then read the book "Meeting Trees" by Scott Russell Sanders. After the book has been read, each student can write down some of the facts that they learned about Ecology in the "L" column.
